Note: In addition, it should be noted that in some educational institutions the teaching of some subjects is conducted remotely, so that the learning process becomes more productive. Especially in cases when a student can’t attend school or university due to illness and a number of other reasons. The percentage of the ratio of traditional hours of instruction and hours of distance learning is determined by each institution and school independently. To summarize, it is worth noting that, in view of the intensive development of computer technologies, increasing the demands of students and young teachers, active development of modern youth – the introduction of electronic education has become an obvious necessity. The use of Internet technologies in the educational system is the key to improving the quality of education not only in our country, but throughout the world.
